Book excerpt: This reference summarizes and tabulates most of the published knowledge of its time, providing a comprehensive presentation of more than 60 elements found in marine organisms. Extensive data, including 327 tables, on various marine groups from planktonic and nonplanktonic algae through fishes should be particularly valuable to investigators in biochemistry and physiology, geology, chemical oceanography, and nutrition. This edition, translated from the original Russian publications by Julia Efron and Jane K. Setlow, contains additional data and observations, not previously published elsewhere, which were added by Vinogradov in the preparation of the translation. The extensive bibliography of more than 2,000 titles was prepared by Virginia Odum.

Available in PDF, EPUB and Kindle. Book excerpt: The chemical basis of the predator/prey relationship, sea stars/bivalves, was examined. Under controlled conditions in a flow-tank, Asterias vulgaris senses intact oysters (Crassostrea virginica) upstream at distances of at least 120 cm. and shows a positive chemotaxis. It responds similarly to aqueous extracts of oyster tissue at concentrations as low as a few parts per billion. The threshold sensitivity of Asterias vulgaris and Asterias forbesi for an oyster extract was compared. It was measured also for A. vulgaris relative to other bivalves. Contamination of the testing tank with particulate suspensions and oil dispersions at concentrations of less than 10 10 mg/liter is sufficient to decrease the response to oyster extract and to lower the threshold sensitivity of the sea stars. A reliable, repeatable method was developed for the partial purification of the oyster extract. Infrared spectroscopy indicates that the major functional groups are -OH, -NH and -COOH. It is probable that the activity is centered in a number of polar, low molecular weight compounds. They are heat stable at 100C, stable to acid, and not hydrolyzable. (Author).

Download or read book Starfish written by John M. Lawrence and published by JHU Press. This book was released on 2013-03-15 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most complete illustrated scientific review of starfish ever published. Among the most fascinating animals in the world’s oceans are the more than 2,000 species of starfish. Called “Asteroids” by scientists who study them (after their taxonomic name, Asteroidea)—or sea stars in some parts of the world—starfish are easily recognized because of their star-like form. Starfish is a comprehensive volume devoted to the integrative and comparative biology and ecology of starfish. Written by the world's leading experts on starfish, the integrative section covers topics such as reproduction, developmental biology and ecology, larval ecology, and the ecological role of starfish as a group. The comparative section considers the biology and ecology of important species such as Acanthaster planci, Heliaster helianthoides, Asterias amurensis, and Pisaster ochraceus. Replete with detailed, scientifically accurate illustrations and the latest research findings, Starfish examines the important role of these invertebrates in the marine environment, a topic of great interest because of their impact on the food web. As major predators that are able to evert their stomach and wrap it around their prey, starfish can have a significant impact on commercial fisheries. Starfish are of interest not only to echinoderm specialists but also to marine biologists and invertebrate zoologists in general and, increasingly, to the medical community. A starfish’s ability to regenerate body parts is almost unequalled in the animal world, making them ideal models for basic science studies on the topic. Contributors: Charles D. Amsler, Bill J.
